Specific embodiment
The application is described in detail below.
In order to solve the problems, such as that perishable aluminium alloy, organic solvent existing for existing cleaning agent are volatile, the application is provided A kind of aqueous cleaning agent, including following components in percentage by weight: sodium citrate 1%~6%;Metasilicate pentahydrate sodium 3%~ 6%;Sodium gluconate 1%~4%;Chelating type dispersing agent 2%~5%;Sodium Polyacrylate 1%~3%;Compound surfactant 3%~8%;Modified succinate 1%~2%;Surplus is water.
Sodium citrate is in cleaning agent technology, auxiliary agent of the alternative sodium tripolyphosphate as without phosphorus cleaning agent, has water-soluble Property is good, to the Ca in water2+、Mg2+Equal metal ions have excellent sequestering power, dispersibility, antiredeposition ability and energy The features such as being biodegradable.In the application, the dosage of sodium citrate accounts for the 1%~6% of total amount, the additional amount mistake of sodium citrate It is more, it will lead to cleaning agent compared with uniform, the stable state that is hard to keep, it is very few also to will affect cleaning effect.
Metasilicate pentahydrate sodium is white crystals sprills, in soluble easily in water and sig water, does not dissolve in pure and mild acid, has and go Dirt, emulsification, dispersion, wet, permeability and pH value buffer capacity.In aqueous cleaning agent provided by the present application, five water metasilicic acids Sodium has the function of degreasing, dosage is 3%~6% as a kind of auxiliary agent.If dosage is excessive, on the one hand it is easy It is precipitated, precipitates in cleaning agent, if on the other hand drift does not wash clean, often have silicon spot residual in workpiece surface, influence cleaning effect Fruit.
Sodium gluconate can assist cleaning workpiece surface blot as highly effective chelating agent, antisludging agent, metal clean, It is widely used in vial cleaning.It is uniform, stable compared with being hard to keep that sodium gluconate additional amount excessively also results in cleaning agent State, it is very few also to will affect cleaning effect.
Optionally, the trade mark of herein described chelating type dispersing agent is DA-P.The chelating type dispersing agent is a kind of modification The powder of methanonaphthalene sulfonate.Methanonaphthalene sulfonate itself has excellent diffusivity, can effectively discrete particles object, and It is soluble in the water of any hardness.The application introduces carboxyl in methanonaphthalene sulfonate structures, since carboxyl is with stronger Chelating ability, so that modified methylene naphthalene sulfonate chelating ability enhances, hence it is evident that improve removal metal surface grey black or other are solid The effect of body particle.In the application, the dosage of chelating type dispersing agent is 2%~5%, if dosage is excessive, not only to cleaning nothing Benefit, and be easy to be precipitated in cleaning agent, precipitate;Dosage is very few, then will affect the cleaning effect of grey black.
Sodium Polyacrylate is dissolved in the media such as cold water, warm water, glycerol, propylene glycol, is stablized to temperature change, is had and is fixed The effect of metal ion can prevent metal ion to the negative consequence of product, be that a kind of surface with a variety of properties is living Property agent.Sodium Polyacrylate increases with relative molecular mass, from colourless weak solution to transparent elastic colloid or even solid.Property, Purposes is also different with relative molecular mass and has significant difference.Herein described Sodium Polyacrylate is the poly- of low relative molecular mass Sodium acrylate, optionally, selecting relative molecular mass is 4500 Sodium Polyacrylate.If selecting relative molecular mass biggish It is unstable to will lead to system for Sodium Polyacrylate, or even the phenomenon that be layered.
Optionally, the trade mark of herein described compound surfactant is 556-W.The compound surfactant include with The component of lower parts by weight: 4~6 parts by weight of isomeric alcohol polyethenoxy ether;1~4 parts by weight of straight chain alcohol polyoxyethylene ether ammonium sulfate salt; Wherein, 1 parts by weight are calculated as based on 1g.
Isomeric alcohol polyethenoxy ether is a multi-functional nonionic surface active agent, has excellent wetting, osmotic energy Power is suitble to metal cleaning;Straight chain alcohol polyoxyethylene ether ammonium sulfate salt is cationic surfactant, has special removing and makees With.The inventors discovered that isomeric alcohol polyethenoxy ether and straight chain alcohol polyoxyethylene ether ammonium sulfate salt have synergistic effect, compounding makes More preferably with rear cleaning performance.In the application, the dosage of compound surfactant is 3%~8%, if improving dosage, needs to add Add more solubilizer that cleaning agent is made to keep uniform, stablize.
Optionally, the compound surfactant is by isomeric alcohol polyethenoxy ether and straight chain alcohol polyoxyethylene ether ammonium sulfate salt It is formulated by weight 5:1.
Optionally, the trade mark of the modified succinate is HY-95.The modified succinate is dodecenyl-succinic acid Acid anhydride hydrolyzed in alkaline condition after product.Modified succinate is a efficient solubilizing agents, so that surfactant and inorganic Salt " compatible ", so that cleaning agent be made to keep uniform, stablize.The formula system needs to add 1%~2%.
From the above technical scheme, this application provides the stamping parts aqueous cleaning agent such as a kind of aluminium alloy, stainless steel, The aqueous cleaning agent has the following characteristics that oil removing, ash disposal are two-in-one, and dirt-removing power is strong, and cleaning speed is fast;Cleaning object range Extensively, including aluminium alloy and stainless steel etc.;In alkalescent, the metal works such as aluminium alloy, stainless steel will not be corroded;It is not phosphorous, favorably In wastewater treatment;Preparation method is simple, easy to operate;Moderate cost.
Optionally, the aqueous cleaning agent includes following components in percentage by weight: sodium citrate 2%~5%;Five water are inclined Sodium metasilicate 3%~5%;Sodium gluconate 1.5%~3%;Chelating type dispersing agent 3%~5%;Sodium Polyacrylate 1%~2%; Compound surfactant 3%~6%;Modified succinate 1%~2%;Surplus is water.
